MARGATE, FL - MARCH 10: Coffee beans are seen in the roaster during the process of making the Miami Beach blend of coffee at the Kana Coffee Roasters on March 10, 2015 in Margate, Florida. A panel of government-appointed scientists at the Dietary Guidelines Advisory Committee charged with proposing changes to U.S. dietary guidelines announced recently that three to five cups of coffee daily do not have long-term health risks, and help reduce the risk for heart disease and type 2 diabetes.
